9 BY Wm WW 19m United States Patent M 3,121,486 KEY AND COIN LUCK FOR CLEANING DEFUSITGRY Robert K. Hensley, In, Hillcrest Heights, Md. (H5 Farmer Drive SE, Washington 22, D.C.) Filed Mar. 20, 195), Ser. No. 800,825 9 Claims. (Cl. 194-54) The present invention generally relates to an improved key and coin lock that is especially adapted for cleaning de ositories but which may be used for other similar purposes having similar problems that must be solved.

The primary object of the present invention is to provide a key and coin lock device for locking and releasing a closure member such as is used on lockers or the like for dry cleaning, laundry or the like so that a customer upon payment of an initial fixed sum may deposit cleaning in the locker or depository and take with him the key for that depository with only a Serviceman then being able to open the depository for removal of the soiled cleaning and replacement thereof after cleaning, the serviceman then conditioning or setting the mechanism for enabling the customer, by depositing any indicated monetary sum, to regain the cleaned clothes by using the key that he originally took with him, the key then being retained in the lock after the customer has obtained his clean clothes therefrom with the lock mechanism being automatically conditioned for subsequent deposit of a fixed sum by another customer.

Another important feature of the present invention is to provide an arrangement in which a portion of the lock mechanism including the key receiving lock may be removed and orientated in other lockers or depositories in a group or bank of lockers or depositories thereby enabling more effective use of the lockers or depositories with the customer only relying upon indicating means on his key and on the movable part of the lock mechanism which may conveniently be numerical indicia for associating the proper key with the proper lock with this function being effectively carried out by providing in the lock mechanism an aperture for engagement over the garment hanger upon which the cleaning is normally deposited so that the cleaning and the lock mechanism which is removable will remain together at all times from the time the Serviceman picks up the dirty clothes until he deposits the clean clothes at which time he inserts the lock mechanism that was carried with the clothes into the closure member operating mechanism that remains with the depository with all of the lock mechanisms being difierent and with all of the closure latching and operating mechanisms being the same.

Yet another object of the present invention is to provide a key and coin lock arrangement which is substantially foolproof in operation, simple in structure in that it contains all mechanical'parts and requires no electrical components, trouble free in operation and relatively easy to maintain.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

Referring now specifically to the drawings, the numeral it? generally designates the coin and key lock mechanism of the present invention for use with a locker or depository generally designated by the numeral 123 which is of a relatively tall, narrow and deep construction and which may be arranged in side-by-side relation into a bank or group such as would occur in various public places and in buildings such as parking buildings or the like. The hollow housing or casing defining the locker 12 is designated by the numeral 14 and is provided with a sliding front closure member 16 having a suitable handle or the like 18 thereon for raising the closure member 18 to a closed position. The lock mechanism It may be in the form of an attachment or may be built into the loc re 12. It is noted that the front wall below the lock mechanism is inwardly tapered as designated by the numeral 20 with the lock mechanism including side walls 22, a front wall 24, a rear wall 28 and a removable top, cover or lid 39. The rear wall 28 overlaps the lower edge of the closure member 16 and has a bracket 32 therein carrying a latch member 34 for pivotal movement about a horizontal axis pin 36 and which includes a keeper or projection 3% which engages an opening it} in the lower end of the closure member 16 and which also extends through an opening 42 in the rear wall 28. The lower end of the pivotal latch 34 is provided with an abutment 44 and a suitable spring is provided for urging the latch member 34 about the pivot pin 36 for registering the projection 38 with the aperture 40 and a stop member 46 is provided for limiting movement of the latch member 34 in this direction. Thus, when the abutment 44- is engaged and moved towards the rear wall 28, the projection 38 will be withdrawn from the aperture 49 in the closure member 16 and the closure member 16 may then be moved downwardly for access into the interior of the locker.

The top or cover 30 is provided with a depending peripheral reinforcing rib 48 which engages the inner surface or" the walls of the lock housing thus positively locating the cover or lid. Adjacent the outer edge of the cover 30 there is provided a key operated lock mechanism 56 which has a horizontal swingable lock arm 52 for engagement under a keeper 54 rigid with the front wall 2 for releasably holding the cover in position. The inner edge of the cover St is provided with a pair of downwardly offset projections for engagement with corresponding notches in the rear wall 28 for positive alignment and locking engagement of the cover with the housmg.

The cover 31} is also provided with a laterally exteriding and upwardly inclined coin chute 56 having instructive indicia 58 thereon for instructing customers to deposit coins in the outer end thereof. The coins roll down the incline of the chute 56 and drop downwardly into a coin receiving means generally designated by the numeral 69 and which includes a pair of vertically elongated strips 62 and 64 both of which are provided with longitudinally extending facing grooves 66 on the inner edges thereof and projecting ribs 68 on the outer edge thereof. The grooves 66 are in alignment with an opening '79 in a transverse member 72 interconnecting the upper ends of the strip members 62 and 64 and underlying the discharge end of the chute 56 whereby coins will be directed downwardly between the strip members 62 and 64. The opening 70 may be slightly tapered and funnel shaped for guiding coins into the grooves or channels 66 between the strips 62 and 64. One wall of the groove 66 in the member 64 is cut away or recessed as indicated by the numeral 74 for permitting coins smaller than the designated diametrical size to fall laterally outwardly of the coin mechanism due to normal lateral movement of the coin during downward movement thereof thus rendering the device incapable of operation except when the proper diametrical size coin is used such as a quarter.

The lower ends of the strip members 62 and 64 are interconnected by a base member 76 and the strip member 62 is provided with a plurality of longitudinally spaced sockets "78 each having numerical indicia 8%) adjacent thereto for indicating the number of coins that will e received within the coin receiving means when the lock m chanism will operate which the serviceman'will set when he deposits the cleaned garments in the depository.

The means'for setting the number of coins include a slide mechanism generally designated by the numeral 32 which includes a block 84 on each side of the strips 62 and edwith a pair of lugs 86 mounting a spring urged catch $8 thereon which has a rounded plunger or pin for engagement selectively in one of the sockets 78. The other of the blocks 84 is provided with a coin release lever 9t pivoted th reon by pivot pin 2 with the block also including an upwardly extending lug 94 disposed exteriorly of the lever with a spring being interposed between the lugs M and the lever 90 for urging the lever into engagement with the strips 62. and 64. The lever 90 is provided with an inwardly extending projection 98 which extends into the area between the strip members 62 and 64 and which will be disposed normally in the path of movement of coins downwardly into the grooves 66. Thus, the projection 98 will stop the coins when it is disposed as shown in FIGURE 15 with any small coins falling laterally outwardly of the recess 74. If the slide is disposed at another position therein, then the coins will not add up to the proper vertical height and further, the recess 74 will normally cause small coins to drop laterally out of the grooves 66 which are spaced properly for receiving quarters only. The end of the lever 9% remote from the pivot pin 92 is provided with an abutment 100 which lies in the path of movement of means for engaging the coin release lever for pivoting the lever 90 outwardly for moving the projection 98 outwardly between the strip members 62 and 64 thus allowing the coins to drop down through the slide mechanism 82 and be deposited on the block 84 on the strip members 62 and 64-. Or" course, the coins may be removed by the serviceman when he services the device and for supporting the coin retaining means 69, there is provided a bracket 102 adjacent the upper end of the side Wall 22 and a bracket Hi4 adjacent the bottom of the side wall 22 for receiving the base '76. The bracket M94 as well as the bracket 162 is provided with grooves for receiving the ribs 68 thus holding the coin receiving means in vertical position. For reinforcing the upper bracket 162, there is provided a pivoted strap res carried by lug bracket 103 with the end of the strap 1% engaging the outer end of the bracket 192 to prevent movement thereof towards the rear wall 28 thereby rigidifying the upper bracket Hi2 and bein swingable upwardly to an out-of-the-way position to permit removal of the coin receiving means 60 for removing the coins and setting the slide and coin receiving mechanism.

For engaging the abutment 109, there is provided an elongated rod 11% having offset ends 112 journaled in sockets within the brackets Hi4- and 192 respectively with the rod 11% being arcuately swingable about a vertical axis defined by the offset ends 112 which arcuate swinging movement will bring the rod into engagement with the abutment lltld regardless of the vertical position of the abutment 1% on the coin receiving carrier en. The upper offset end 112 of the rod lit: extends through the bracket 102 as illustrated in FIGURE 2.

Extending through the fornt wall 24 is an elongated hollow guide 114 which is rectangular in cross-sectional configuration and which extends for a major part of its length within the interior of the housing defined by the walls with the guide 114 slidably receiving an elongated slide bolt 116 which has an upwardly extending handle or lug 118 on the outer end therof for enabling the same to be pushed inwardly and pulled outwardly. The bolt 11s is of the same cross-sectional configuration as the guide 114. FEGURE 14 illustrates the construction of the bolt which includes an upstanding pin 12% thereon in spaced relation to the inner end thereof together with a screw threaded socket 122 adjacent the pin 12:!) but slightly nearer the handle forming lug 118 and spaced laterally from the pin 12%). One side edge of the bolt 116 is provided with a longitudinally extending groove 12% therein and the top surface of the bolt lld is provided with a recess 26 extending longitudinally having an upwardly inclined end surface 128 forming a cam for a purpose described hereinafter. The pin 12% is re- 7 ceivcd in an elongated slot 13%? in the lid and overa screw threaded bolt 134 which may be shouldered and which is provided with a sleeve 136 thereon which is rotatable between the headed end 138 of the bolt and the guide 114. Carried by the sleeve 136 is a pivotal arm 140 which extends outwardly and terminates in a generally olfset terminal end l t-2 having an adjustable abutment member 14% on the outer end thereof which will move through the area between the strips 62 and 64- and will feel or sense coins therein. If coins are disposed therein in the path of movement of the abutment 144, the abutment 144 will be held from further movement and upon continued movement of the bolt inwardly, the arm 140 will swing about the bolt 134- until the abutment 146 comes into contact with a projection 14% on the upper bracket 102 in which the upper end 112 of rod 119 pivots whereupon the arm 14%) may continue to pivot about the bolt 134 thereby permitting the bolt 116 to slide on inwardly with the inner end thereof coming into engagement with the abutment 4 6 for releasing the latch 34 in an obvious manner. If no coins were present, then the projection or abutrnent ll it would engage the outer edge of the projection thus preventing pivotal or swinging movement of the arm 14% and preventing further inward movement of the bolt 116.

The arm 14! is provided with a spring 150 connected to the upstanding pin 120 and to a fastener at the apex of the arm 14b and the offset end 142 for normally urging the arm 149 into perpendicular relation to the sliding bolt 116.

The bolt 116 is also provided with a laterally projecting pin 152 which extends outwardly through a slot 154 in the guide lid and which will engage the rod 11%) when the bolt 116 moves all the way in thereby moving the coin release lever 9% to coin releasing position as illustrated in FIGURE 13. A return spring 156 is connected to pin 152 and a suitable bracket on the front wall 24 thus urging the bolt lie to its outer position.

The front wall 24 is provided with a removable lock plate loll which is provided with grooved bottom and side edges 162 for sliding engagement in a notch in the front wall 24 wherein the lock plate lot) may be easily removed by lifting the same and sliding the same vertically upwardly. Mounted in the lock plate 169 is a key operated lock mechanism 164 provided with a key tee with both the lock plate 16:) and key 165 having corresponding indicia such as a corresponding number so that the proper key may be associated with the proper lock mechanism. The lock mechanism is provided with a laterally extending arm .63 which will engage a notch 17% in the bolt 7.16 through a slot 2'172 extending vertically through the guide 114. The body 174 which rotatably supports the arm 168 also engages a spring 1'76 having one end terminally attached to a corner fastener 178 on the arm 16% and the other end connected to a fastener 13% cmried by the plate lot; whereby the arm res will be urged to a vertical position. The arm tea is also provided with an inwardly extending pin 182 for a purpose described hereinafter.

Slidably mounted on the side edge of the guide 114 is a slidable bracket 164 having a pivotal tongue 186 connected thereto and spring urged to a position with the free edge thereof lying against the side edge of the guide lid as illustrated in FIGURE 2 when in this condition. The bracket 184- is provided with inturned lugs 13% engaging longitudinal grooves 195) in the top and bottom walls or": the guide 114. The tongue 1% is provided with a projecting pin 192 adapted to extend through a slot in the guide and into the slot 124 in the sliding bolt 116, whereby the bracket 134 will be moved inwardly when the bolt 116 is moved inwardly. Pivotally mounted on bracket 194 is a generally L-shaped latch member 1% iounted by pivot pin 1% and having a fiat bowed leaf spring 26% urging one end of the L-shaped latch member 1% downwardly towards the top of the guide. The free end or" the latch member 196 is provided with a projecting pin 2% which extends downwardly through an opening in the guide 114 and engages the cam recess 126 and particularly the cam end 128 thereof whereby the sliding bolt will cause upward movement of this end of the lat I1 136 when the bolt 116 moves inwardly thereby causing downward movement of the other end of the latch 1%. The other end of the latch 196 is provided with a laterally extending and upturned hook shaped end portion which will engage the lower edge of the tongue 186 thus retaining the tongue 186 in retracted position generally alongside of the latch member 196 substantially as illustrated in FIGURE 12.

The top cover 3b is provided with an indicator open ing 2% having a closure member of transparent material 293 which may be glass or plastic. Underlying the indicating opening 2% is a supporting bracket or plate 21% rotatably supporting a disk or wheel 212 which has a portion of the periphery thereof extending beyond the plate with the periphery being knurled or otherwise roughened for permittin" rotation of the wheel 212. The wheel M2 is provided with a series of indentations 214 for engagement by a ball detent 216 which is spring urged by spring 218 thus retaining the wheel 212 in rotatably adjusted position. The wheel IE2 is provided with a plurality of circumferentially arranged numbers 218 comparable to the numbers 8% appearing on the coin carrying means. lso carried by the bracket 21%) is a slidable L-shaped member 2 21} which has two longitudinally ar ranged portions with one portion thereof having the word vacant printed thereon as indicated by the numeral 222 with the other portion having the word quarters as designated by the numeral 224 printed along the bottom edge thereof with the top edge having an opening for revealing the numbers ZlS on the disk or wheel 212. The depending flange on the L-shaped indicator 220 is provided with a notch 226 which receives the projecting pin or peg 182 on the lock ann 168 which will automatically move the indicator to the proper indicating position upon proper operation of the device with the serviceman being responsible for rotating the disk 212 so that the proper number of coins will be indicated so that the customer will deposit the proper number of coins when he obtains the cleaned garments. Also, the lock arm is provided with an aperture whereby the lock mechanism may be engaged over the hook of a conventional garment hanger so that the lock mechanism may be taken with the hanger and maintained with the garment while being cleaned.

in operation, the empty locker will be conditioned as illustrated in FIGURE 2. in this condition, the bolt 11s cannot be pushed inwardly since there is no coin to initiate pivotal movement of the arm 14% thus, the abutment M6 will lock with the outer edge of the projection 14%. The key of counts will be in the lock mechanism. When a quarter is inserted into the coin chute, the lock bolt 1:16 maybe pushed in. i t is also pointed out that the key 166 cannot be removed since it is of the type that cannot be removed until the arm is swung to a horizontal position and this cannot occur in view of the position of the bracket 134 and tongue 1%. Upon inward movement of the lock bolt 116 which can occur after a quarter has been deposited, the arm 14-9 is swung rearwardly as indicated in FIGURE 10 and at the same time the coin release meohanism or lever has released the coin and the closure door has been released. Also, note that the pin 1% has engaged with the slot 124 and moved the bracket inwardly out of the path of movement of the lock arm whereby the lock arm may engage the notch 17% in the bolt lib when the bolt is withdrawn. The bracket 1% does not move back outwardly with the bolt 11-6 since the length of the slot 124 is sufiioient to allow the bracket to maintain its innermost position. By turning the lock arm to the locked position, the key 166 may then be taken by the customer that has just deposited the cleaning in the receptacle through the opening formed by oneness the closure member and, of course, the customer closes the closure member by raising the same. No one else can have access to the locker since no one elses key will fit. The Serviceman then comes and opens the device by removing t-.e top lid and pressing on latch in an obvious manner. When he does this, he also removes the coin from the coin receiving means and sets the slide 252 to the desired number of quarters and also sets the disk 212. it may be added that when the lock arm 16% was moved to the locke position, the l..-shapcd member 22% was moved laterally so that the vacant portion was no longer visible and only the quarters indicia was visible. As illustrated in FlGURE 7, the device is set up for receiving one quarter when the customer returns for his cleaned gait .ent thus making two quarters total for the cleaning. The serviceman will remove the garment along with the lock plate 16d and assemble the lock plate with the garment on the hanger and the entire assembly will go to the cleaning plant. This enables the sewiceman to use the same locker several times during the period of cleaning since it is only necessary for him to insert another lock plate to put the locker back into service. When the servicemen brings the cleaned garment back, he places it in a loc, or which may be one that ie has just removed soiled garments from and places the lock plate back into the front plate 24. He then sets the disk 21?. and sets the slide mechanism 82 correspondingly and also sets the bracket 184 with the tongue 1% engaged with the hook shaped end 164 of the latch 19 a; as illustrated in FIGURE 12. The customer after matching his key with the lock will insert the indicated number of coins and when the proper number of coins have been inse ted as well as the key which allows the lock arm to swing up, the bolt Tilt; may be pushed inwardly since the abutment 144 will engage a coin rendering the arm 1% swingable rear-weirdly so that the abutment 146 will engage the face of the projection 14% facing the front wall thus allowing continued movement of the bolt 116 inwardly. During the initial movement of the bolt 1116 inwardly, the cam 12% will engage the projection 2% thus lowering the hook shaped end 2% and releasing the tongue 1% so that it is spring biased back to a position alongside of the slide lid with the pin 1% engaging the bolt lilo outwardly of the slot 124 thereby leaving the bracket 1% overlying notch 17?. thus preventing subsequent removal of key. When the lock arm swings back to a vertical position, the pin 132 engages the indicator and tiles it over so that the vacant sign is once more revealed and indicating that the device is again ready for use. Of course, when the lock bolt was pushed in the closure door was released and the person obtained his cleaned garments and closed the closure member. The coins which were dropped in by the customer when he retrieved his cleaned garments also were dropped down the distance of one quarter or whatever distance determined by the construction of the slide which in this instance is constructed to allow the coins to move down a distance equal to the diameter of a single quarter, by release of the coin release lever when the bolt 116 was pushed inwardly.

in order to prevent sliding movement or" the bracket 18% on the guide 114 by tilting and shaking the entire device'which would ena le removal of the key without depositing a coin, there is provided a bracket rigid with the guide ful and including a bowed leaf spring 232 which will en age the tongue and stop the bracket 134 before it slides beyond the notch in th e lid.

The foregoing, is considered as illustrative only of the principles of the invention. Further, since nuir rous modifications and changes will readily occur to .t e skilled in th art, it is not desired to limit the invei. i
